Shipping question

I need some guidance on shipping. I am selling albums and stickers.

For albums, the cost will be $5 flat rate USPS media mail shipping for between 1 and 3 albums and then $1 extra for each album above that.

For stickers, those are $2. If they order at least one album and stickers then I don’t need to charge them shipping for the other sticker(s).

What formula do I use? Right now I am doing…
5.00 * [qty] for albums
and for stickers 2.00
but that doesn’t accomplish what I need. Does this plugin accomplish this?
